Forms of Hypothesis

Bruce W. Tuckman lists these hypothesis types:

1. Question form

The simplest empirical observation is a question-based hypothesis. It fails most hypothesis definitions. It’s often listed. Instead of dichotomizing hypotheses into accept/reject categories, simple investigations can be done by asking a question.

2. Declarative Statement  

Declarative hypotheses predict variable relationships. A hypothesis developer has examined existing evidence and believes a difference may be expected as additional evidence. It states how the independent variables affect the criterion variable.

3. Directional Hypothesis

A directional hypothesis predicts the relationship between variables. This hypothesis developer seems more confident in expected evidence. This hypothesis is riskier than others because it suggests two conditions. First, that the variable relationship problem is so obvious that additional evidence is scarce.

Second, the researcher has thoroughly examined variables, and the evidence supports a particular anticipated outcome.

4. Non –Directional Hypothesis or Null Hypothesis

The null hypothesis states that the variables are unrelated. Probability theory tests null hypothesis. Non-directional hypothesis.

Most research uses null hypothesis. Null hypotheses suggest no difference based on evidence. The alternative and differences are unknown if the null hypothesis is rejected.

The researcher need not predict or explain the declaration or directional form.
